Answer:

2 hours and 32.7 minutes. This is a good problem to become familiar with. It comes up in physics quite frequently.

Step-by-step explanation:

1 job/4 hours + 1 job / 7 hours = 1/x

1/4 + 1/7 = 1/x

(7 + 4)/28 = 1/x

11/28 = 1/x

x / 1 = 28/11

x = 2.54 hours repeating.

1 hour = 60 minutes

0.54 hours = x minutes

1/.54 = 60/x

x = 0.54 * 60

x = 32.7 minutes
